7. Practice: Understanding Traits and Genes
Question 4
You're conducting a science experiment crossing two different purebred mouse strains, which
each contain a different variation of the same gene, for two generations. What do you expect to
see as the phenotypes of the first generation? What about the second generation?

Final answer:

Genotypes and phenotypes are linked in genetics, Punnett squares help predict offspring traits, mutations influence allele variation.


Explanation:

Genotypes and phenotypes are connected in dominant and recessive gene systems. The genotypes determine the genetic makeup, while the phenotypes are the observable physical traits.

In a monohybrid cross, a Punnett square is used to calculate the expected proportions of genotypes and phenotypes in offspring. A test cross is performed to determine the genotype of an individual expressing a dominant trait.

Mutations can lead to variations in alleles, which can affect natural selection and introduce chance events in genetic inheritance.
